10		That was my initial approach. The reasoning behind going with a new customizer setting was that setting the widget instance to false was causing failures in sanitation (WP_Customize_Widgets->sanitize_widget_instance()).

Additionally I feel the intention is more clear when a widget is added to a deletion array.
